Abstract

The utility model discloses an intelligent early warning safety helmet. The top of the safety helmet is provided with an early warning device; and the early warning device comprises an ultrasonic emitter, an ultrasonic receiver, a signal processor, an alarm and the like. The ultrasonic emitter constantly emits ultrasonic waves over the top of the intelligent early warning safety helmet, the ultrasonic waves are reflected by barriers, received by the ultrasonic receiver and analyzed by the signal processor, and if ultrasonic signals received by the ultrasonic receiver become intense, the alarm gives an alarm and generates vibration to remind a safety helmet wearer. The intelligent early warning safety helmet is simple in structure, practical and convenient, an intelligent early warning function of the safety helmet is increased, and the safety helmet has the safety protection capacity.

Description

An intelligent early warning safety helmet

technical field

The utility model relates to a safety helmet, in particular to an intelligent early warning safety helmet.

Background technique

Safety helmets are widely used in engineering construction, emergency rescue and disaster relief, and factory operations. The function of the safety helmet is that when the operator is impacted or squeezed by high-altitude falling objects or hard objects, it can reduce the impact force and eliminate or reduce its damage to the human head. But this protection is limited, and existing helmet generally does not have the function of safety early warning.

Contents of the invention

The purpose of the utility model is to provide a safety helmet with both protective capability and early warning function.

In order to solve the above technical problems, an early warning device is provided on the top of the smart early warning safety helmet described in the utility model, and the early warning device is composed of an ultrasonic transmitter, an ultrasonic receiver, a signal processor, an alarm and the like. The ultrasonic transmitter continuously emits ultrasonic waves directly above the top of the early warning helmet, and is received by the ultrasonic receiver after being reflected by obstacles. After analysis by the signal processor, if the ultrasonic signal received by the ultrasonic receiver increases rapidly, the alarm will be triggered and the alarm will be triggered at the same time. Vibration is generated to alert the helmet wearer.

Because the utility model adopts the above-mentioned design, its structure is simple, practical and convenient, and the intelligent early warning function of the helmet is added, so that it has more safety protection ability.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1, Fig. 2 are the structural representations of a kind of intelligent early warning safety helmet of the present utility model.

Fig. 3 is a structural block diagram of an early warning device of an intelligent early warning safety helmet of the present invention.

In the figure: 1. Safety helmet, 2. Early warning device, 3. Ultrasonic transmitter, 4. Ultrasonic receiver, 5. Signal processor, 6. Alarm, 7. Power supply, 8. Switch.

Detailed ways

Below in conjunction with accompanying drawing, the utility model will be further described:

As shown in FIGS. 1 and 2 , the early warning device 2 is fixed on the top of the safety helmet 1 . The composition of the early warning device 2 is shown in FIG. 3 . In Fig. 3, the ultrasonic transmitter 3, the ultrasonic receiver 4 and the alarm 6 are connected to the signal processor 5 respectively, the switch 8 is used to control the on-off of the power supply 7, and the alarm 6 is used to sound an alarm and generate vibration.

Turn on the power switch 8, the ultrasonic transmitter 3 in the early warning device 2 continuously transmits ultrasonic signals directly above the safety helmet 1, and the ultrasonic receiver 4 is used to receive ultrasonic signals reflected back by obstacles. When an object fell from the sky and approached the helmet wearer, the ultrasonic signal emitted by the ultrasonic transmitter 3 was reflected by the object and received by the ultrasonic receiver 4. When the signal processor 5 analyzed the signal received by the ultrasonic receiver 4, the more When getting stronger, trigger alarm 6 to report to the police and vibrate to remind the safety helmet wearer.

Claims (2)
